Ruby on Rails チュートリアルのユーザー機能作成あたりまでをほぼ自動化するシェルスクリプト

※文章によるまとめを断念しました。代わりにシェルスクリプトを作成したので、ここに置いておきます

# 概要
Ruby on Rails チュートリアルにも書いてあるとおり、多くのWEBアプリケーションでユーザー機能はあって当然と言える。逆に言えば、WEBアプリケーション開発の始まりは、ユーザー機能作成が終わってから、とも言えるのでそこまでをほぼ自動化した。

「俺たちの戦いはこれからだ！～ご愛読ありがとうございました。（以下略」にならないように、せいぜいかんばりましょう

# 動作環境
* Windows/Mac（Windows環境しか動作確認していません）
* VirtualBoxインストール済
* Vagrantインストール済

# 内容
Ruby on Rails チュートリアルのUser機能作成あたりまでをほぼ自動化する

# 手順
## 1. 何はともあれ、前編を終わらす
[Ruby on Rails チュートリアルの第1章、環境構築までをほぼ自動化するシェルスクリプト](http://qiita.com/histori/items/ace1e5b224f5fd8f868b)を終わらせる
## 2. 前編で作成したフォルダ内に次のファイルを置く
* static_pages.sh
* users.sh

それぞれのファイルの変数は適当な内容に変更する

```bash:static_pages.sh
#!/bin/sh

# シェルスクリプト内で使う変数

（な、長い...）

## 3. 仕上げる
1. ターミナルから仮想マシンに、ID/PW:vagrantでログインする
2. `$ sh /vagrant/static_pages.sh`
3. `$ sh /vagrant/users.sh`

これで終わりだが、念のための動作テスト
1. アプリケーションディレクトリに移動する
2. `$ bundle exec rspec spec/requests/static_pages_spec.rb`
3. `$ bundle exec rspec spec/requests/user_pages_spec.rb`
4. `$ bundle exec rspec spec/requests/authentication_pages_spec.rb`
5. `$ bundle exec rspec spec/models/user_spec.rb`
